CAR-COUPLING LINK.

SPECIFICATION forming part of Letters Patent No. 275,460, dated April 10, 1883.

- Application filed October 18. 1882. (No model.)

To all whom it may concern Be it known that I, JOHN BRIDGE, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Oar-Coupling Links; and Ido hereby declare that the following is a full,

clear, and exact description thereof, referencebeing bad to the accompanying drawing, which form a part of this specification.

The nature of this invention relates to certain new and useful improvements in car-links, by means of which greater strength is obtained at the ends of the links, where they come in contact with the couplin g-pin usually employed for that purpose in coupling railway-cars together. r

The ordinary method of manufacturing such links ist-o cut a bar of iron ot' the proper size intoblanks, each of which is of sufficientlength to form a link. This is then bent in the center,jforming a U shape. The free ends are then bent toward each other and welded togetherf'so that both ends of the link present the e appearance in form. This method mg links leaves them much stronger at thg 'welded end than at the opposite end, for inthe' process of bending at the center the molecules or crystals of the iron are disturbed and deranged by being drawn upon the outer face and com pressed,with ateudency to buckle together upon the inner face of the bent end.

The object of the invention is therefore to manufacture a car-coupling link that will be ofequal strength at the opposite ends, whereby the tendency to break in the bent end. of the link as ordinarily constructed, and where shch breakage almost always occurs, is avoided:

In the accompanying drawing my improved car-link is shown. This link is made by cut"- ting the blanks half the required length, so that two of such blanks are required to form the peifect link. Both ends of these sections are bent inwardly, and the opposite adjacent ends are welded then in the ordinary manner, ac

cofnplishing the result which I desire to att in- What I claim as my invention is--- As; a. new article of manufacture, a c0up= ling-link formed of two pieces welded at each end by hammering, whereby such ends, where the" wrenching strain comes when in use, are greatly strengthened, substantially as and for 'tl e'purposes set forth.

JOHN BRIDGE.
